TABLE 2 TO PARAGRAPH (d)—SCHEDULE OF MATERIALS ANNUAL FEES AND FEES FOR GOVERNMENT AGENCIES LICENSED

BY NRC—Continued 

[See footnotes at end of table] 

Category of materials licenses Annual fees 123

A. Certificates of Compliance ................................................................................................................................................. 10 2,174,000 

B. Uranium Mill Tailings Radiation Control Act (UMTRCA) activities [Program Code(s): 03237, 03238] ............................ 271,000 

1Annual fees will be assessed based on whether a licensee held a valid license with the NRC authorizing possession and use of radioactive 

material during the current FY. The annual fee is waived for those materials licenses and holders of certificates, registrations, and approvals who 

either filed for termination of their licenses or approvals or filed for possession only/storage licenses before October 1 of the current FY, and permanently ceased licensed activities entirely before this date. Annual fees for licensees who filed for termination of a license, downgrade of a license, or for a possession-only license during the FY and for new licenses issued during the FY will be prorated in accordance with the provisions of § 171.17. If a person holds more than one license, certificate, registration, or approval, the annual fee(s) will be assessed for each license, certificate, registration, or approval held by that person. For licenses that authorize more than one activity on a single license (e.g., 

human use and irradiator activities), annual fees will be assessed for each category applicable to the license. 2Payment of the prescribed annual fee does not automatically renew the license, certificate, registration, or approval for which the fee is paid. 

Renewal applications must be filed in accordance with the requirements of parts 30, 40, 70, 71, 72, or 76 of this chapter. 3Each FY, fees for these materials licenses will be calculated and assessed in accordance with § 171.13 and will be published in the FEDERAL

REGISTER for notice and comment. 4Other facilities include licenses for extraction of metals, heavy metals, and rare earths. 

5There are no existing NRC licenses in these fee categories. If NRC issues a license for these categories, the Commission will consider establishing an annual fee for this type of license. 6Standardized spent fuel facilities, 10 CFR parts 71 and 72 Certificates of Compliance and related Quality Assurance program approvals, and 

special reviews, such as topical reports, are not assessed an annual fee because the generic costs of regulating these activities are primarily attributable to users of the designs, certificates, and topical reports. 7 Licensees in this category are not assessed an annual fee because they are charged an annual fee in other categories while they are licensed to operate. 8 No annual fee is charged because it is not practical to administer due to the relatively short life or temporary nature of the license. 9Separate annual fees will not be assessed for pacemaker licenses issued to medical institutions that also hold nuclear medicine licenses 

under fee categories 7.A, 7.A.1, 7.A.2, 7.B., 7.B.1, 7.B.2, 7.C, 7.C.1, or 7.C.2. 10This includes Certificates of Compliance issued to the DOE that are not funded from the Nuclear Waste Fund. 11See § 171.15(c). 12See § 171.15(c). 13 No annual fee is charged for this category because the cost of the general license registration program applicable to licenses in this category will be recovered through 10 CFR part 170 fees. 14Persons who possess radium sources that are used for operational purposes in another fee category are not also subject to the fees in this 

category. (This exception does not apply if the radium sources are possessed for storage only.) 15 Licensees subject to fees under categories 1.A., 1.B., 1.E., 2.A., and licensees paying fees under fee category 17 must pay the largest applicable fee and are not subject to additional fees listed in this table. 16 Licensees paying fees under 3.C. are not subject to fees under 2.B. for possession and shielding authorized on the same license. 17 Licensees paying fees under 7.A, 7.A.1, 7.A.2, 7.B, 7.B.1, 7.B.2, 7.C, 7.C.1, or 7.C.2 are not subject to fees under 2.B. for possession and 

shielding authorized on the same license. 18 Licensees paying fees under 3.N. are not subject to paying fees under 3.P., 3.P.1, or 3.P.2 for calibration or leak testing services authorized 

on the same license. 19 Licensees paying fees under 7.B., 7.B.1, or 7.B.2 are not subject to paying fees under 7.C., 7.C.1, or 7.C.2 for broad scope license licenses 

issued under parts 30, 35, 40, and 70 of this chapter for human use of byproduct material, source material, and/or special nuclear material, except licenses for byproduct material, source material, or special nuclear material in sealed sources contained in teletherapy devices authorized 

on the same license. 20 No annual fee is charged for a materials license (or part of a materials license) that has transitioned to this fee category because the decommissioning costs will be recovered through 10 CFR part 170 fees, but annual fees may be charged for other activities authorized under the license that are not in decommissioning status. 21 Licensees paying fees under 4.A., 4.B. or 4.C. are not subject to paying fees under 3.N. licenses that authorize services for other licensees 

authorized on the same license.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

The Boeing Company Model 787–8, 


ddrumheller on DSK120RN23PROD with PROPOSALS1
12786 Federal Register / Vol. 89, No. 34 / Tuesday, February 20, 2024 / Proposed Rules 

787–9, and 787–10 airplanes. This 

proposed AD was prompted by a report 

of heat damage on multiple engine 

inlets around the engine anti-ice (EAI) 

duct within the inlet aft compartment. 

This proposed AD would require doing 

a records check and updating the 

operator’s existing minimum equipment 

list (MEL), inspecting the left and right 

engine inlet cowl assembly for signs of 

heat damage around the EAI duct, 

installing or replacing the EAI duct 

seals, repairing any damage, and 

replacing the engine inlet if necessary. 

This proposed AD would also prohibit 

the installation of engine inlets under 

certain conditions. The FAA is 

proposing this AD to address the unsafe 

condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by April 5, 2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

SUPPLEMENTARY INFORMATION: 

Comments Invited 

The FAA invites you to send any 

written relevant data, views, or 

arguments about this proposal. Send 

your comments to an address listed 

under ADDRESSES. Include ‘‘Docket No. 

FAA–2024–0231; Project Identifier AD– 

2023–01037–T’’ at the beginning of your 

comments. The most helpful comments 

reference a specific portion of the 

proposal, explain the reason for any 

recommended change, and include 

supporting data. The FAA will consider 

all comments received by the closing 

date and may amend this proposal 

because of those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to 

regulations.gov, including any personal 

information you provide. The agency 

will also post a report summarizing each 

substantive verbal contact received 

about this NPRM. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Tak Kobayashi, 

Aviation Safety Engineer, FAA, 2200 

South 216th St., Des Moines, WA 98198; 

telephone 206–231–3553; email 

takahisa.kobayashi@faa.gov. Any 

commentary that the FAA receives that 

is not specifically designated as CBI will 

be placed in the public docket for this 

rulemaking. 

Background 

The FAA has received a report 

indicating that damage was found 

during overhaul on multiple inlets 

around the EAI duct within the inlet aft 

compartment. After investigation, it was 

found that the seals between the inner 

and outer ducts and between the outer 

duct and the aft compartment were 

missing. This led to EAI air leaking into 

the aft compartment exposing inlet 

components to high temperatures. This 

condition, if not addressed, could cause 

damage around the EAI duct, leading to 

reduced structural strength and 

departure of the inlet from the airplane, 

resulting in subsequent loss of 

continued safe flight and landing or 

injury to occupants from a departed 

inlet contacting the airplane. 

FAA’s Determination 

The FAA is issuing this NPRM after 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin B787–81205– 

SB540023–00 RB, Issue 001, dated 

September 22, 2023; and Boeing Alert 

Requirements Bulletin B787–81205– 

SB540024–00 RB, Issue 001, dated 

September 22, 2023. This service 

information specifies procedures for 

incorporating (or verifying 

incorporation of) an updated dispatch 

deviation guide (DDG) for item 30–21– 

01–02 into the operator’s existing MEL, 

checking records to determine whether 

the inlet has been dispatched under 

MEL item 30–21–01–02 or 30–21–01–07 

before incorporation of the DDG 30–21– 

01–02 update, and applicable related 

investigative and corrective actions, 

including general visual inspection for 

signs of heat damage around the EAI 

duct, conductivity measurement and 

hardness test of areas with heat damage, 

replacement/installation of the periseal 

and aft seal, and repair or replacement 

of the engine inlet. These documents are 

distinct since they apply to different 

airplane configurations. This service 

information is reasonably available 

because the interested parties have 

access to it through their normal course 

of business or by the means identified 

in ADDRESSES. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

the service information already 

described, except as specified under 

‘‘Difference Between this Proposed AD 

and the Service Information’’ and except 

for any differences identified as 

exceptions in the regulatory text of this 

proposed AD. This proposed AD would 


ddrumheller on DSK120RN23PROD with PROPOSALS1
Federal Register / Vol. 89, No. 34 / Tuesday, February 20, 2024 / Proposed Rules 12787 

also prohibit the installation of affected 

parts under certain conditions. For 

information on the procedures and 

compliance times, see this service 

information at regulations.gov under 

Docket No. FAA–2024–0231. 

Difference Between This Proposed AD 

and the Service Information 

The applicability in this proposed AD 

is not limited to the airplanes identified 

in paragraph A., ‘‘Effectivity,’’ of Boeing 

Alert Requirements Bulletin B787– 

81205–SB540023–00 RB or Boeing Alert 

Requirements Bulletin B787–81205– 

SB540024–00 RB, both Issue 001 and 

both dated September 22, 2023. This 

service information does not contain a 

complete list of all airplanes that may be 

affected by the identified unsafe 

condition. Therefore, the applicability 

of this proposed AD is all Model 787– 

8, 787–9, and 787–10 airplanes. 

Interim Action 

The FAA considers that this proposed 

AD would be an interim action. An 

investigation is ongoing. If final action 

is later identified, the FAA might 

consider further rulemaking then. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 110 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

MEL update and records check ...................... 5 work-hours × $85 per hour = $425 ............. $0 $425 $46,750 

The FAA estimates the following 

costs to do any investigative actions or 

repairs/replacements that would be 

required based on the results of the 

records check. The agency has no way 

of determining the number of airplanes 

that might need these actions: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Inspection ..................................................................... 3 work-hours × $85 per hour = $255 ........................... $0 $255 

The FAA has received no definitive 

data on which to base the cost estimates 

for the conductivity measurement, the 

hardness test, inlet replacement, and 

installation of a new periseal and aft 

seal, as specified in this proposed AD. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

The FAA is issuing this rulemaking 

under the authority described in 

Subtitle VII, Part A, Subpart III, Section 

44701: General requirements. Under 

that section, Congress charges the FAA 

with promoting safe flight of civil 

aircraft in air commerce by prescribing 

regulations for practices, methods, and 

procedures the Administrator finds 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority because it addresses an 

unsafe condition that is likely to exist or 

develop on products identified in this 

rulemaking action. 

Regulatory Findings 

The FAA determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would not 

have a substantial direct effect on the 

States, on the relationship between the 

national Government and the States, or 

on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Would not affect intrastate 

aviation in Alaska, and 

(3) Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

The Boeing Company: Docket No. FAA– 

2024–0231; Project Identifier AD–2023– 

01037–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by April 5, 

2024. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all The Boeing 

Company Model 787–8, 787–9, and 787–10 

airplanes, certificated in any category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 54, Nacelles/pylons. 

(e) Unsafe Condition 

This AD was prompted by a report of heat 

damage on multiple engine inlets around the 


ddrumheller on DSK120RN23PROD with PROPOSALS1
12788 Federal Register / Vol. 89, No. 34 / Tuesday, February 20, 2024 / Proposed Rules 

engine anti-ice (EAI) duct within the inlet aft 

compartment due to missing seals between 

the inner and outer ducts and between the 

outer duct and the aft compartment. The 

FAA is issuing this AD to address EAI air 

leaking into aft compartment exposing inlet 

components to high temperatures, which 

could result in damage around the EAI duct. 

This condition, if not addressed, could lead 

to reduced structural strength and departure 

of the inlet from the airplane, resulting in 

subsequent loss of continued safe flight and 

landing or injury to occupants from a 

departed inlet contacting the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions
